  1. Hi Mate, Check out Pro Tunerz in Ottawa Canada. They are making a Turbo manifold now. https://www.autoyas.com/CA/Ottawa/1681949728590008/ProTunerz Regards David
  2. Hi, The wiring to the solenoid goes through the key switch wiring which is 40 years old. The connections become a problem over time not allowing full voltage to the starter solenoid. A starter relay should be wired in so the old wiring though the switch is only used to activate the relay. The relay kit is available on Ebay, Z car Source , Motorsport etc sites or just make your own. Wiring diagrams will be available on this site. Hope this helps Enzo
  3. Hi, That's the hot air intake and attached from the exhaust manifold to the bottom of the air cleaner. It redirects hot air the prevent the carbs icing up in winter (cold climates). The correct air cleaner will have a sensor and valve device which will mix the air drawn into the carbs at a set temperature to stop icing up. Also keeps the emissions reduced and stops condensation build-up in the valve cover. Cheers David.
  4. Looking good. Very impressive. Paint looks a million dollars.💰
  5. Hi Lowrider, I will be looking for your results with the CB Performance Black Box. I got one sent downunder to Australia to use on a 240z. The original dizzy was stuffed so I found a good points Hitachi dizzy and locked it up internally and disconnected the broken vacuum diaphragm. The points were removed and replaced with a Hot Spark ignition module.(Similar to Pertronic). I have stalled on the project, so it will be a while before I can complete my setup. The price was good , and I liked the flexibility of the advance curve plus the use of vacuum advance all electronically. David.
  6. Hi Guys, The ignition lock has pins. The door and hatch have wafers. Trying to replace pins and wafers on old locks is false economy. The main part of the cylinder wears over the years with the key sliding in and out. Even if you replace the pins and wafers to match your key, the lock will still have wear in it possibly allowing other keys to open the lock. You would be better off just buying a replacement group of keyed alike cylinders off ebay or your local Locksmith. I have replaced the pin cylinder in the ignition of my 1976 260z with a wafer cylinder to keep all of my locks keyed alike. I
  7. Hi Derek, I read a report years ago that having the mesh screens on a race car engine only allowed dust and rubber particules from the soft compound racing tyres (as they degrade)from close proximity racing to be sucked into the combustion chamber and from the intense heat turn sticky and collect behind rings etc. From memory, there were pictures showing the gummy residue (mixture of dust and rubber). It was suggested the filters should be used to stop the bore being scratched and the residue build-up behind the rings. If I can find the article, I will post it. They mesh has a macho tough look
  8. Hi, Looking at you Adds as listed in the first post, to me it reads as Nissan parts. Maybe it's as simple as changing your add to read " will fit Nissan (whatever model)". or "suits Datsun". Just a thought. Wording of an add can change buyers perception. Hope you get it sorted. regards David.
  9. Hi, Just a thought. If you are getting a spark at the plug and fuel is present, Check that the valve adjustment is correct. If the valves are not closing all the way you will have a miss on that cylinder. If the valve clearances are correct do a compression test in that cylinder to see if you have a bent valve that is not closing all the way. David
  10. Hi Brent, Still haven't got around to firing mine up at the moment, but have some extra info for you. You have probably already onto this, but I will repeat it anyway for people not in the know. From FiTech: 1. The pressure regulator on the Fuel Command Centre (FCC) which the original instructions said to leave open on a normally aspirated engine is now recommended to connect to manifold pressure. This can be done at the Throttle Body or direct to the manifold. This lowers the fuel pressure when at idle and cruising conditions when high pressure is not
  11. Hi Brent, Same here. Looked at rotating the throttle body but it was in the "too hard basket". It didn't line up easily with the Arizona Z manifold. Probably a bit of overkill but with the alloy plate and extra phenolic spacer, I should have maximum shielding for the IAC. Also the back set of throttles don't seem to open the full 90 degrees. There is something in the installation paperwork about not adjusting the linkages as they are set at the factory.
  12. Hi Brent, I spoke to you recently on Auszcar about your installation. I have attached a picture of what I have done regarding the heat from the headers. I haven't included a picture of a thin stainless steel plate attached to the manifold bolts in the middle section where you have the excess heat wrapping but that is my first shield. Then is the alloy plate over the inlet manifold. Then a White Phenolic plate at 6mm which can be seen that goes back towards the valve cover. The throttle body is then placed on top. Gaskets are between the manifold and alloy plate/ phenolic plate/
  13. Hi Mate, Check out the rubber diaphragm in the mechanical pump. If it has a small split it will still supply fuel at low rpms but get worse as you drive. As the split get bigger fuel starvation will get worse. Also check you oil and see if it smells of fuel. Regards David.
  14. Opps!!! I stand corrected. Newzed is spot on. My brain wasn't switched on. ( I could say being from a land down under that I was looking at everything in reverse).LOL. I will delete my first confusing post. David.
  15. Hi, First picture. Listen to NewZed, he is correct.
